Collaboration is the process of two or more people, entities or organizations working together to complete a task or achieve a goal. Collaboration is similar to cooperation. Most collaboration requires leadership, although the form of leadership can be social within a decentralized and egalitarian group. Teams that work collaboratively often access greater resources, recognition and rewards when facing competition for finite resources. Collaboration is present in opposing goals exhibiting the notion of adversarial collaboration, though this is not a common use of the term.
